SPLICE-BAR FOR RAILROAD-RAILS.

FBPECIFICATION forming part of Letters Patent No. 375,193. dated December 20, 1887.

Application filed May 6, 1887. Serial No. 237,324. (No model.)

To aZZ whom it may concern:

Be it known that I, JONAS POTTER, of Morrellville, in the county of Oambria and State of Pennsylvania, have invented a new and Improved Splice-Bar for Railroad-Bails, of which the following is a full, clear, and exact description.

My invention relates to an improvement in splice-bars for railway-rails, and has for its object to provide a simple, economical, and effective means of splicing the rails and securing them to the sleepers.

The invention consists in the construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a plan view of the splice-bar Fig. 2is a bottom plan of an end view of the rail, and Fig. 3 is a transverse vertical section through line 0c 5c of Fig. 1.

In carrying out the invention the bar A, preferably rectangular in form, about thirty inches long and six inches wide, is provided for each joint of the rails, having a series of integral chairs, B B, preferably three in number, of a height equal to the distance between the extreme base of the rail and the under projecting surface of the tread. The end chairs, B, are preferably made about five inches in length and the center chair ten inches, the distance intervening the inner perpendicular faces, I), of the chairs being equal to the thickness of the web B of the rail. The outer faces, I), of the chairs are preferably rounded off or inclined downward, and the ends thereof are perpendicular. Each outer edge, a, of the plate A, in central alignment with the chairs, is provided with a rectangular slot, a, in which slots spikes are entered, adapted to be driven in the sleepers to retain the plate A in position.

At each end of the rails D the flanged portion of the base is cut away flush with the web upon each side to form the splice d, thelength of said splice being equal to about half the length of the chair B, namely, about five inches.

The flange of the base is not disturbed for about a distance of five inches to the rear of the splice d, which represents the distance 5 intervening the edges of the chairs B B, and then the said flange is cut away to form an inner splice, d", which splice is of a-leugth equivalent to the length of the chair B.

In operation each section of rail, with their ends abutting, are placed in the chairs, the chairs B receiving the end splice, d, of each rail, and the chairs B the inner splices, d of the respective sections, the upper end of said chairs supporting the tread of the rail, and the base-flange of the said rail filling the space intervening the respective chairs B andv the chair B.

Four apertures, O, are provided in the plate A upon each side, the inner edges of said ap- 73 ertures being in vertical alignment with the edge of the rail at the base. Into each aperture O a spike is entered and driven in the sleeper, the head of the spike clamping the flanged base of the rail, holding it in secure 75 contact with the plate and providing an auxiliary fastening for said plate to the sleepers.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A splice-bar for railroad-rails, consisting of a plate provided with a central chair and end chairs of less length than the central chair, said chairs being spaced equidistant, substantially as set forth.

'2. A railroad-rail having its base cut away to the face of the web at each side to form opposite rabbets in said base at the end, and recesses beyond said rabbets, substantially as shown and described. 9o

3. In a splice-bar for railroad-rails, the combination, with the plate A, provided with in tegral equidistanced chairs B B, of a section of rail provided with an end splice, d, and an inner splice, d, substantially as shown and de- 5 scribed.

4. In a splice for railroad-rails, the combination, with the plate A, provided with end chairs, B, and a central chair, B, of greater length than said end chairs, of abutting sec- 5 tions of rail provided with a splice, (1, at their ends equal to one-half the length of said chair B, and an inner splice, d equal to the entire length of the chairs B, and means for securing the said rails and plate, substantially as shown and described.
